[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0022] Embodiments of the present utility model:

[0023] The utility model provides a switchgear busbar contact detection device, including the base 1 of the section is the shape of omega, and the corner of base 1 is all seted up mounting hole, and fixed bolt 12 is passed through mounting hole and is connected with switchgear (not shown in drawing) with thread, through the cooperation of fixed bolt 12 and mounting hole, the function of being imprisoned to base 1 is played.

[0024] The center of the top of base 1 is provided with an adjusting groove 2 in a linear direction, and the adjusting groove 2 is internally provided with an adjusting column 3. The adjusting column 3 can not only move and rotate in the length direction inside the adjusting groove 2, but also can be finely adjusted up and down inside the adjusting groove 2, thereby having strong flexibility. It should be noted that the connecting part of the adjusting column 3 and the adjusting groove 2 is provided with a locking assembly 4. Through the setting of the locking assembly 4, the adjusting column 3 is fastened to prevent the adjusting column 3 from shaking during use.

[0025] Specifically, the locking assembly 4 includes two nuts 41, and the two nuts 41 are respectively located at the upper and lower parts of the adjusting groove 2. The two nuts 41 rotate in opposite directions, thereby fastening the adjusting column 3. It should be noted that the side of the nut 41 close to the base 1 is provided with a gasket 42, and the outer diameter of the gasket 42 is much larger than the width of the adjusting groove 2. Through the setting of the gasket 42, the contact area with the base 1 can be increased, thereby playing a fastening role to prevent the adjusting column 3 from shaking during use.

[0026] The top end of the adjusting column 3 is fixed with an "L"-shaped adjusting rod 5, and the adjusting rod 5 is horizontally slidably installed with a mounting seat 6, so that the mounting seat 6 can be adjusted according to the position of the branch bus. It should be noted that the number of mounting seats 6 is not limited, and normally one mounting seat 6 can be installed on the adjusting rod 5. The detection element 7 at the bottom of the mounting seat 6 can detect the branch bus 11. If multiple branch buses 13 are installed inside the switch cabinet, and the arrangement of the multiple branch buses 13 is allowed, multiple mounting seats 6 can be installed on the adjusting rod 5, and multiple detection elements 7 at the bottom of the multiple mounting seats 6 can detect multiple branch buses 11 respectively. The bottom end of the mounting seat 6 is installed with the detection element 7, and the detection element 7 is a contact temperature sensor. The signal S318-11C55 of the contact temperature sensor can detect the temperature of the end of the branch bus 11 through the detection element 7. The output end of the detection element 7 is electrically connected to the input end of a controller (not shown in the figure) through a wire. The controller is a single-chip microcomputer, and the model of the single-chip microcomputer is HT66F018. The controller is installed inside the switch cabinet, and the output end of the controller is electrically connected to an alarm installed on the outer wall of the switch cabinet through a wire. The alarm can be a buzzer or an alarm lamp. When the detection element 7 detects an abnormal temperature of the branch bus 11, the detection element 7 can transmit the detected signal to the controller, and the controller controls the alarm again to make the alarm send an alarm signal and notify the staff, so that the staff can take corresponding measures in time to avoid potential safety hazards.

[0027] It should be noted that a limiting groove 9 is formed on the outer surface of the adjusting rod 5 in a straight line direction, and a limiting protrusion 10 is fixed inside the mounting seat 6 and slidably installed in the limiting groove 9. Through the limiting groove 9 and the limiting protrusion 10, the mounting seat 6 is limited to prevent rotation during use.

[0028] When installing the detection device, if the space beside the branch bus 11 is narrow, the base 1 can be installed in a position with relatively large space, and then the adjusting rod 5 is adjusted according to the position of the branch bus 11, so that the adjusting rod 5 can drive the adjusting column 3 to move, rotate or fine-tune up and down in the adjusting groove 2. After adjustment (as shown in Figure 1 The two nuts 41 are rotated in opposite directions to tighten the adjusting column 3, and then the mounting seat 6 is pushed to drive the detection element 7 to move horizontally. If the detection element 7 contacts the end of the branch bus 11, the butterfly bolt 8 is rotated again to make one end of the butterfly bolt 8 abut against the outer surface of the adjusting rod 5, thereby achieving the function of tightening the mounting seat 6.

[0029] If the switch cabinet is internally installed with multiple branch busbars 11, and the detection ends of the multiple branch busbars 11 are connected in a straight line a which is parallel to the axis b of the adjusting rod 5 (as shown in Figure 2 Fig. 6); multiple mounting seats 6 can be installed on the adjusting rod 5, each mounting seat 6 can be adjusted according to the position of the branch busbar 11, so that when the detection element 7 at the bottom end of the mounting seat 6 is in contact with the branch busbar 11, the mounting seat 6 is fastened by the butterfly bolt 8.

[0030] If the temperature value of the branch busbar 11 reaches the set value of the detection element 7, the detection element 7 can transmit the detected information to the controller, and the controller can control the alarm to issue an alarm signal and notify the staff, so that the staff can take corresponding measures in time to avoid safety hazards.
